Siver Plastic Testing Equipment HDT Vicat Tester for ASTM D 648 Heat Deflection Temperature Test
Standard:
Accord with ASTM-D648 JIS-K7191 ISO-2507 GB/T 8802 test standard requirements.
Scope of application:
Mainly applicable to the determination of plastic test pieces, thermal deformation HDT... Three-point loading under the bending stress deformation temperature and plastic Vicat softening temperature test method ... plastic samples under the specified conditions, the needle penetration phenomenon temperature.
Principle:
The test machine can choose to use compressor cooling or water cooling. Compressor cooling with high efficiency can achieve rapid cooling effect, and save water consumption during water cooling. All metal materials immersed in high-temperature heat transfer oil are alloy steels with low deformation coefficient, which minimizes high-temperature deformation of the material and improves the accuracy of test results.
Main features:
It has the functions of heating up, cooling down, and stirring automatic control, automatically displaying the measuring point temperature. The high-precision LVDT displacement sensor is used to measure the deformation of the indenter, and with the high-speed iron's self-developed deformation sensing amplifier, the high resolution and accurate sensing do not jump.
